[Training Camp] WS2812 Xiaoai classmates glare base 694846A

#小爱精品Ambient light base

## 1.

I bought two Xiaoai classmates, one black and one white, for the background, one for playing and the other for the universal remote control version. I felt it was not fancy enough, so I took the opportunity to learn how to drive the WS2812 light strip. The first version is made with Arduino. It should not be too simple to call the FastLed library. Take advantage of the training camp between Lichuang and Tuya Smart to learn about the entire process of IoT device development.
